ICE-MAKING APPARATUS;

Application filed November 8, 19195 Serial No. 336,558.

I which are placed in or near a freezing soluadvantageous features, some of which, to-

tion.

One of the objects of this invention is to provide a fluid conductor to be assembled with the freezing can; the conductor, preferably a tube, will form a conduit for the fluid, generally air under pressure, to the bottom of the freezing can. The fluid after passing into the can will rise and thereby keep the impurities in the water agitated so that they will not be included in the ice.

Another and important object of this in vention is to assemble the tube with the freezing can so that the tube does not enter the can thereby avoiding all injury tube and its holding means during the formation of the ice and the removal of the ice cake.

This inventionpossesses many other and gether with the foregoing, will be set out more at length in the following description wherein will be outlined in full that form of the invention which has been selected for illustration in the drawings accompanying and forming a part of the present specification. i

The attached drawing which forms a part of this application illustratesone of the preferred embodiments of'the invention, where- Figure 1 is a perspective view of the freezin can.

Tigure 2 is a sect-ion thereof taken below the reinforcing band at the top.

Figure 4 is asecti'onal view of a side of the can, of a conducting means and a reinforcing member.

In ice making apparatus, referring particularly to the container for forming cakes of ice, there has been employed a means for to the 1 one of'the 1,422,935 rarest o conducting a fluid from'the top of the can to the bottom thereof and allowing the exit of the fluid into the water to be congealed thereby keeping the impurities in the water moving so that they will not be included in the resulting frozen cake of ice. Several means have been employed in order to conduct this fluid to the'bottom of the can. It is advisable not to have the conducting means or tube enter the freezing can but to have an opening in the side thereof through which the fluid ma'ypass directly into the water to be congealed. By keeping-the tubes on the outside of the cans they will not be' injured during the process of freezing or by the removalof the ice cake from the can. In

the practical use of these ice freezing cans,

it is preferable to have a smooth interior surface so that the ice willhave a uniform shape and the ice cake will be easily removed from the can. If there are project-ions on the inner surfaces of the can extending into the can for varied dlstances, shoulders Wlll' be formed-1n the ice and will prevent the cake from being easily removed.

The invention herein disclosed and described providesfor a' channel formed in one of the sides of the can and having such channel extend from the top toward the bottom of the can, and having the fluid conduit assembled in this channel but not to extend into the can to form an indentation in the 108' which will prevent the quick removal of the ice from the can. 4

Referring to the figures, there is shown in Figure 1 the freezing can 1 which has the base 2 and the four'sides. The top edge of the can is reinforcedby a flange 3 which to the of the Prefermay be a separate piece attached sldes, or may be a continuous part sides turned back onthemselves.

ably, the freezing cans are made of metal" but this invention is not limited to the mate rial employed. A channel a is formed in one of the sides so that a fluid conducting means or tube 5 may be assembled therein. This channel extends from the top of the side to" substantially the bottom thereof. The chan nel may be formed in one ofthe shorter sides so that the fluid may pass from the tube 5 across the longest part of the base of the can. It is to be understood that the channel may be in any one of the other sides of the can or may be in all four sides if desirable, and tubes assembled in such channel or channels. Channels without tubes may be formed in any of the sides. The ice freezing can as herein disclosed is of the rectangular shape, but the invention is not limited there to. However, if other designs of freezing cans are employed, it may be advisable to have the fluid directed across the longest distance between the sides at the bottom of the can.

The conducting means may be a tube or pipe or any other fluid tight material of pipe construction. There is provided on the side in which the channel is formed, protecting members 6 which protect the tube and assist in maintaining it in normal position. A general conception of the location of the channel and conducting tube is obtained from Figures 2 and 3, the latter showing more in detail the preferred design of the channel and tube. The channel L as shown in Figure 3 is of the substantially semi-circular cross section and receives a tube 5.

which is of circular cross section, but the designs of the channel and the tube may be varied to produce other desirable features, and it is to be understood that this invention is not limited to the design illustrated. The tube 5 may be surrounded by a non-conductor of heat, if desired.

The formation of the lower end of the channel and the contacting therewith of the tube or pipe is readily appreciated by reference to Figure 4: where the side 7 shows a portion of the channel 4; and the reception therein of the pipe 5. Since these freezing cans are preferably made of metal, the metal may be readily pressed into various forms and the edge of the base 2 of the can in this instance is of Ushape form having the two upright portions 8 and 9. The center interior base portion 10 is generally higher from the floor or supporting member than the bottom edges of the U-shaped portion. The sides of the can are received by the U-shaped portion and are held in position by rivets 11. The channel in the side of the can terminates just above the plane of the base 10 and there forms a shoulder or end wall 12 through which anopening 13 is inade. The opening 13 in the shoulder registers withthe natural opening 1 1 in the fluid conduit and Such conduit is supported by shoulder 12, and it is not necessaryto bend the pipe in manner in order to assemble the same with the freezing can.

The formation of the channel t and the opening 13 therein may be formed at the same time as the stamping of the side from the sheet metal and by this method of manufacture there is a considerable reduction in the production time required and the expense of labor. The pipe 5 can readily be assembled in the channel 4 and it is not necessary to fabricate the pipe in any manner as the opening 13 registers with the opening 14: of the pipe and the pipe may be soldered onto the Shoulder 0r may be attached thereto in any other desired manner. The pipe may also be soldered to the can at arious points along its length. The upper end of the pipe may haveannular protruding beads to assist in holding a flexible hose connection to the pipe or, if desired, any other attaching means may be employed. The protecting pieces 6 assist in protecting the pipe and maintain the pipe in position. These pieces may be spot welded in position or may be riveted or held by any other wellknown attaching means. The opening 13 in channel 4 may be stamped therein at any desirable angle, the essential feature being that it registers or coincides with the opening 14 of the pipe.

It will be understood that the embodiment of the invention herein described and shown in the accompanying drawings may be variously modified, and that the present invention is susceptible of different embodi; ments. In so far as such modifications and embodiments of the invention come within the scope of the following claim they are considered to be within the scope of the invention.

I claim:

A freezing can having a channel formed vertically in one wall thereof, said channel being of identical cross section from the top of the can to a point adjacent the base where said channel is provided with a perforated end wall forming an acute angle with the base and presenting a flat portion surrounding the perforation, a straight air tube mounted in said channel and extending from end to end thereof, the tube presenting an upper end open for connection with an air supply pipe and presenting a flat diagonal lower end fitting against the corresponding flat portion of the end wall of the channel around the perforation and soldered thereto to provide an air-tight conduit to the inte rior of the can, whereby air may be introduced into said can and directed across the bottom thereof to agitate the contained water during the freezing operation.

In testimony whereof, I have signed my name to this specification this fifth day of November 1919.
